SPECIFICATION forming part of Letters Patent No. 669,817, dated March12, 1901.

Application filed January 10, 1901. Serial No. 42,708. (No model.)

To ctlZ whom it may concern:

Be it known that I, SYLVESTER J. ASBELL, a citizen of the United States,residing in Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Right and Left HandStop and Waste Cocks; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to cooks for water and gas pipes, 850.; and ithas reference particularly to devices of this nature known as stop andwaste cocks.

The object of the invention is to construct a stop and waste cock sothat it may be reversed with despatch and convenience and at the sametime be as simple, compact, and durable in construction as possible.

The invention is fully illustrated in the accompanying drawings, whereincorresponding letters of reference indicate like parts, and wherein--Figures 1 and 2 are views in side elevation of my improved stop andwaste cock provided with one form of detent for limiting the movement ofthe plug which in said figures is shown in respectively open and closedpositions by the breaking away of a portion of the casing of the device.Figs. 3 and 4 are respectivelya side view and a top plan view of saidcock with the handle and detent removed. Fig. 5is a top plan View of thebandle and detent shown in Figs. 1 and 2. Figs. 6 and7 are respectivelya rear and a top plan View of the upper portion of a cock provided withanother form of detent, and Fig. 8 is a side view of the upper portionof the improved cock as adapted for operation by a T- shaped handle orkey.

In said drawings, a designates the casing of the cook, the same being ofordinary construction and having the usual pipe connections b and c andwaste-outlet d.

6 denotes the usual tapered plug or valve, having the ordinary main portf and wasteport g, the latter communicating with the former. Said plugis secured in place by a said stops nut h, which is screwed onto thelower protruding and threaded end thereof, its upper end protruding fromthe usual crown i, which crown is formed with stops jj and 7a. The stopsj j are disposed a little to one side of the longitudinal centralline ofthe cock, while the other stop 7c is disposed midway between The top ofthe plug 6 is squared or of some other non-circular form, as at 1, beingadapted to receive a handle on or a T-shaped key it, both of these partsbeing provided with a socket portion 0, having a recess 19 to fit thesquared head of the plug. Said socket portion is provided with aprojection g. This projection may be formed either with a pair ofvertical parallel ribs r, forming guides, or with a pair of threadedvertical orifices s.

The detent which I provide may be in two forms. In the one case itconsists of asquared block 25, adapted to snugly fit between the ribs rand having a lug it. projecting down wardly from one of its cornersintothe space between the stop and one of the stopsj. This detent is securedin place by a screw c, which penetrates it, and is adapted to be screwedinto the side of the socket of the key or handle and into the threadedorifice w in the head of the plug. The screw thus acts to secure thehandle or key in place on the head of the plug. In the other case thedetent is simply in the form of a screw 00, which may be tapped intoeither of the threaded orifices s of the projection (1. In this case thehandle or key may be secured in place by a separate set-screw y, whichis tapped into the socket portion and takes against the head of the plugin either of two diametrically-disposed notches 2 thereof.

In reversing the cock when provided with that form of detent firstdescribed the handle having been removed and replaced on the head of theplug in a diametrically-reversed position the detent is removed, turnedover, and reapplied, so that its lug will now work in the space on theside of the stopj opposite to thatin which it previously worked. Inreversing the cock when provided with the other form of detent, havingremoved and reversed the handle, the screw w is withdrawn from oneorifice s and inserted into the other.

If desired, and as shown in Figs. 3 and 4, the

.head of the valve-stem may be formed With both the orifices w andrecessesz, so as to aocommodate a handle orkey whether the one or theother form of det'ent and securing means for the handle is carried bysaid handle.

Having thus fully described my invention, What Iclaim as new, and desireto secure by Letters Patent, is

1. In a stop and waste cook, the combination, With the casing, of a turnplug or valve arranged in said casing, said casing having pairs of stopsarranged about said plug or valve, a handle fitted to said valve orplug, and a detent adapted to engage said stops to limit the motion ofsaid plug or valve, said detent being mou nted interchangeablyin saidhandle so as to engage the stops in either pair of stops, substantiallyas described.

2. 'In a stop and waste cook, the combination, with the casing, of aturn plug or valve arranged in said casing and protruding therefrom atone end, said casing having pairs of stops arranged about the protrudingend of said plug or valve, a handle fitted to the protruding end ofsaid. plug or valve, and a detent adapted to engage said stops to limitthe motion of said plug or valve, said detent being mountedinterchangeably in saidhandle so as to engage the stops in either pairof stops, substantially as described.

3. In a stop and waste cock, the combination, with the casing, of a turnplug or valve arranged in said casing and protruding therefrom at itsupper end, said casing having pairs of stops arranged about said plug orvalve, a handle fitted to the protruding end of said plug or valve andhaving a projection, and a detent adapted to engage said stops to limitthe motion of said plug or valve, said detent being mountedinterchangeably in said projection so as to engage the stops in eitherpair of stops, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this31st day of December, 1900.
